why do feet swell diabetes

Swelling in the feet of diabetic patients may stem from nerve and vascular damage due to elevated blood glucose levels. This condition impairs blood circulation, leading to fluid accumulation in tissues and resulting in swelling.

In more detail, diabetes can precipitate several scenarios that trigger foot swelling:

Firstly, high blood glucose levels can harm the microvasculature, including the blood vessels in the kidneys. This impairment affects the kidneys' capacity to filter out excess fluids and salts, causing fluid retention and swelling.

Secondly, diabetic neuropathy might diminish the activity of foot muscles, disrupting the normal flow of lymphatic fluid—a protein-rich fluid that clears cellular waste. Obstructed lymphatic flow can also result in fluid buildup and swelling.

Additionally, chronic hyperglycemia can lead to heart disease and hypertension, both of which compound the difficulty of the heart in pumping blood to the legs, further intensifying foot swelling.

Hence, for individuals with diabetes, managing blood glucose levels is crucial for preventing foot swelling. Regular foot health checks, maintaining appropriate exercise, wearing well-fitted shoes, and elevating the feet to enhance blood circulation are also essential. Persistent foot swelling or the presence of additional symptoms warrants timely medical consultation and professional medical advice and treatment.
